simple example of a containerized Node.js endpoint mimicking an interview question I was asked
All packages used in this example are built in to Nodejs so there are no dependencies.
After installing Nodejs, you are ready to go.
To run simply execute node webserver.js after cloning the repository.
Once the webserver is running on your local machine, go to url http://localhost:8080/weather?ID=1 to see the working example.
After starting the program and hitting the endpoint, expect an output similar to this:
>> Initializing server on port: 8080
>> Retrieiving data @ ID: 1
A successful hit to the endpoint will return a mock temp as JSON object. An unsuccessful hit will return an error in JSON format as well.
Because the source code is finished and the docker file is complete, you only need to build the image using the docker CLI.
$ docker build -t <your_username>/node-web-app .
Finally, run the image and expose it to port 80.
$ docker run -p 80:8080 -d <your_username>/node-web-app
You can now access the webserver at http://localhost/weather?ID=1
A successful hit to the endpoint will return a mock temp as JSON object. An unsuccessful hit will return an error in JSON format.
First, pull my image from docker hub.
$ docker pull chsclarke11/node-web-app
Run the image and expose it to port 80.
$ docker run -p 80:8080 -d chsclarke11/node-web-app
You can now access the webserver at http://localhost/weather?ID=1
A successful hit to the endpoint will return a mock temp as JSON object. An unsuccessful hit will return an error in JSON format.
the REST service is functional only at the /weather endpoint. It accepts IDs 1, 2, and 3. All other inputs (or no inputs) will be handled with an error similar to the following: { "ERROR" : "tempId does not exist"}. If you access an unknown endpoint you will be redirected to a 404 page (for those accessing this on a browser). Finally, index.html exists but has no content. Future iterations would involve displaying this readme on index.html
thank you!
